This place saved my big tube headers. Superior Welding Punta Gorda FL 941 639 2966
Or buy new AFTER MARKET CMI's. Don't buy the Mercury. You will see that After-markets are heavier.
Offshore Performance Specialties Fort Myers FL (239) 489-0884 call Donney he has very good prices.

While I do not have 700,s or CMI's on my boat if I did this is what I would do.

How that company hasn't had a class action lawsuit is beyond me. Without question one of the worst high performance boating products to ever be marketed. I'd replace them with anything other than CMI.

Perfect Storm
Did you go back with CMI mercury headers or did you get non mercury CMI headers.
A good friend of mine said CMI headers are fine just dont get the ones mercury has CMI build to there specs.
If you put mercury CMI on did you have any trouble after you installed the mercury CMI new headers?

Donny said mercury improved there headers in 09 re-did the collector area and its been 4 years and he has not saw any go bad but OMG he wants $5500 a set x 2 $11000.00 I am now saying I cant afford them I just think thats a little high for 2 sets

during off season
1. pull out all fuel injectors get flowed
2. pressure or water test headers
3. remove all old fuel
3. replace water pumps and change oil in fuel pump assembly replace mechanical fuel pumps if gas is present
4. leak motors down
5. if seaweed is present in intercoolers remove and send to radiator shop or re-install (install better sea strainer just for intercoolers to end this process.
5. new mercury fuel filters and water separators.
This is annual maintenance every year to keep from breaking down in the middle of a season when I do this ever year we are able to make it to 6 or more poker runs a year and play on our lake 95% time trouble free
